OK, I typed you suggested and I got proper answer.

Thanks, Miroslav !!

Arigato!

[root@xxxx ~]# sesearch -A -s httpd_sys_script_t -p name_bind -C

On my fedora20 box, I tried to check Bash Expoit as Dan did on his latest blog post.

What I got is,

Found 12 semantic av rules:

Though 12 rules caught by sesearch, but none displayed.

Yes, this is expected. It is allowed only by booleans.

$ sesearch -A -s httpd_sys_script_t -p name_bind -C

 Next I typed,

[root@xxxx ~]# sesearch -A -s httpd_sys_script_t -p name_connect -C | grep -v ^D
Found 24 semantic av rules:

This is ok.

What's wrong with name_bind thing?

I use
setools-console                    x86_64                    3.3.7-41.fc20
